Preparation method of blocky zirconium-carbon composite aerogel material
The invention belongs to the field of preparation processes of nanometer porous materials, and relates to a preparation method of a blocky zirconium-carbon composite aerogel material. With resorcinol and formaldehyde as the carbon source, inorganic zirconium salt zirconium oxychloride as a zirconium source, deionized water as a hydrolytic agent, alcohols as solvent and epoxide as a gel accelerator, under the effect of a basic catalyst, wet gel is prepared through sol-gel reaction, and the blocky high-temperature-resistant zirconium-carbon composite aerogel material is obtained after ageing, solvent displacement, supercritical drying and high-heat treatment are conducted on the wet gel. The material prepared with the cheap inorganic zirconium salt as the raw material is low in density, large in specific surface area, high in strength, resistant to high temperature and complete in structure, and the system has good prospects on the aspect of high-temperature thermal insulation and the aspect of serving as catalytic carriers.
